摘要： The present invention relates to a method for measuring and controlling the short circulation of a paper machine or equivalent and measurement and control of the headbox, said short circulation comprising apparatus for diluting thick stock into the headbox consistency, and apparatus for cleaning the stock to be fed into the headbox, and in which the headbox (10) comprises a stock inlet header, a tube bank, a turbulence generator and a slice channel. In the method, the measurement targets (PA, PB, PC, PD, 10) are provided with means for measuring the fibre mobility of the fibre suspension and, on the basis of the fibre mobility measured from the fibre suspension, the flow state of the fibre suspension is controlled. The invention also concerns the headbox (10) of a paper machine or equivalent, comprising a stock inlet header, a tube bank, a turbulence generator and a slice channel. In addition, the headbox comprises sensors on the width of the headbox (10) or a traversing sensor/sensors, which is/are positioned on different width points of the headbox (10) and that the sensor/sensors is/are arranged to measure the fibre mobility profile of the headbox and that the headbox (10) comprises means for changing the flow state on the basis of the measurement data obtained from the sensors. The invention also relates to a short circulation of a paper machine or equivalent, comprising apparatus for diluting the thick stock into headbox consistency and units for cleaning the stock to be fed into the headbox. The short circulation comprises also a sensor/sensors, being disposed in the short circulation pipes and/or cleaning units and that the sensor/sensors is/are arranged to measure the fibre mobility of the fibre suspension in the short circulation, and that the short circulation includes means for changing the flow state on the basis of the measurement data obtained from the sensors.

摘要： The invention concerns a multi-layer headbox (10) for a paper/board machine, comprising stock inlet headers (J1, J2...) for the stocks (M1, M2...). The inlet headers communicate with a tube tank (11) and through the tube bank with an intermediate chamber (E1, E2...), from which the stock flows further into the turbulence generator (12) and through the pipes (12a1.1, 12a1.2..., 12a2.1, 12a2.2...) in the turbulence generator (12) further into the slice cone (13) and onto the forming wire (H). The multi-layer headbox comprises, across the width of the headbox, distribution valves (V1, V2...) for dilution water, each of which distribution valves (V1, V2...) communicates with a distribution plate (16) placed in connection with the tube bank (11), in which connection, from one valve (V1, V2...), the dilution liquid is distributed at the same time to at least two of the stocks (M1, M2...) that from the different layers of the web in the multi-layer headbox.

摘要： The invention relates to a method of mixing pulp components in the manufacture of paper, in which method the pulp components to be mixed are led to a mixing point (S) along tubes arranged inside each other. The pulp component flows are mixed by generating turbulence in them by means of the end of an inner tube (2; 2a to 2c), the cross-section of which end is wave-like. This turbulence is guided and its effect is intensified by means of form parts (4a to 4c) in connection with the mixing point, which form parts are arranged on the inner surface of the outer tube. Further, the invention relates to an arrangement implementing the mixing of pulp components in accordance with the method.
